Keep in mind that these numbers are not simply based on how many iPhones have sold. The 50% number includes "Related Products and Services" such as carrier agreements, services, and accessories. Anything brought from the App Store is classified as iTunes revenue. iPod Touch and the iPad were not calculated as a part of the iPhone revenue.

On their Results call yesterday, they said that:1) Mac sales continued to increase year-over-year;2) Analysts have predicted a ~3% decrease in the PC market this year;3) 50% of Macs sold were sold to first-time buyers;

What does this mean? In plain terms, they are slowly winning a larger portion of a slightly-shrinking pie, and 50% of their sales are going to people buying their first mac. As I recall, the story has been pretty similar for the last few years. The iPhone/iPad/iPod halo effect, I suppose.

Will everybody be using a Mac tomorrow, or next month? No, of course not. But there's very little reason to conclude that Macs are dead, or even feeling a little under the weather.

Why can't I go by OS and platform? Is there some rule that says that isn't allowed? I mean you want comparables you have to look at Smartphones by OS. I mean even Nielsen put their ratings for Smartphones like that. Why would anybody reasonably try to compare Smartphones to MP3 players?

When people compare Windows marketshare to Apple they don't break out Dell, HP, Lenovo, etc. and they don't try to group XBox in with Desktops.
